[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application provides an aerosol generating device, such as... Figures 1-6As shown, the aerosol generating device includes: a housing 1, a liquid supply device 2, and an atomizing device 3. The liquid supply device 2 and the atomizing device 3 are mounted side by side on the housing 1. The liquid supply device 2 has a storage cavity 21. The atomizing device 3 is connected to the liquid supply device 2. The two ends of the housing 1 are respectively provided with an air inlet 11 and an air outlet 12. The atomizing device 3 is provided with an atomizing channel 31 and a ventilation channel arranged at intervals. The atomizing channel 31 connects the air inlet 11 and the air outlet 12. The ventilation channel connects the storage cavity 21, the air outlet 12, and the air inlet 11.

[0032] The working principle of the aerosol generating device provided in this application embodiment is as follows: the storage chamber 21 is pre-loaded with an aerosol generating medium, which is used to provide the aerosol generating medium to the atomizing device 3; when the user draws through the air outlet 12, the external gas enters the atomizing channel 31 through the air inlet 11, the atomizing device 3 heats the aerosol generating medium to generate aerosol, and the aerosol is discharged outward through the air outlet 12; when the aerosol generating medium in the storage chamber 21 of the liquid supply device 2 decreases and forms a negative pressure, external air can be introduced through the ventilation channel to balance the air pressure inside and outside the liquid supply device 2, thereby ensuring sufficient liquid supply to the atomizing device 3.

[0033] The beneficial effects of the aerosol generating device provided in this application embodiment are as follows: the air exchange channel in this application can balance the internal and external air pressure of the liquid supply device 2, reduce the flow resistance of the aerosol generating medium, and enable the aerosol generating medium to be continuously and stably supplied to the atomizing device 3, avoiding insufficient liquid supply or leakage of the aerosol generating medium, thereby avoiding poor atomization effect or dry burning.

[0034] like Figures 2-5 As shown, further, the liquid supply device 2 has a through hole 22 communicating with the storage cavity 21 on one side; the atomizing device 3 includes a mounting shell 32, a liquid guiding cotton assembly 33, and an atomizing core 34; the mounting shell 32 has a mounting cylinder 35 on one side, the mounting cylinder 35 is connected to the through hole 22 and communicates with the storage cavity 21, the liquid guiding cotton assembly 33 is disposed in the mounting shell 32, and at least part of the liquid guiding cotton assembly 33 is disposed in the mounting cylinder 35, a first ventilation groove 4 is provided between the liquid guiding cotton assembly 33 and the mounting shell 32, the first ventilation groove 4 communicates with the air inlet 11 and the air outlet 12, a second ventilation groove 5 is provided between the liquid guiding cotton assembly 33 and the mounting cylinder 35, the second ventilation groove 5 communicates with the storage cavity 21 and the first ventilation groove 4, the first ventilation groove 4 and the second ventilation groove 5 communicate to form the ventilation channel, and the atomizing channel 31 passes through both ends of the middle part of the liquid guiding cotton assembly 33.

[0035] In this embodiment, when the user draws air through the air outlet 12, external gas enters the atomization channel 31 through the air inlet 11. The aerosol generating medium in the liquid supply device 2 flows to the atomizing core 34 through the liquid guiding cotton component 33. The atomizing core 34 heats the aerosol generating medium to generate aerosol, and the aerosol is discharged outward through the air outlet 12.

[0036] In this embodiment, a second ventilation groove 5 is provided between the liquid-guiding cotton assembly 33 and the mounting cylinder 35, which can effectively guide the aerosol generating medium from the storage chamber 21 to the atomizing core 34; at the same time, when the aerosol generating medium in the storage chamber 21 of the liquid supply device 2 decreases and forms a negative pressure, external air can be introduced through the first ventilation channel and the second ventilation channel to balance the air pressure inside and outside the liquid supply device 2, thereby ensuring sufficient liquid supply to the atomizing device 3.

[0037] In this embodiment, the atomizing device 3 and the liquid supply device 2 are connected together by the mounting cylinder 35, and the positioning between the atomizing device 3 and the liquid supply device 2 can be realized.

[0038] like Figures 4-6 As shown, the liquid-guiding cotton assembly 33 further includes a first liquid-guiding cotton 331 and a second liquid-guiding cotton 332. The first liquid-guiding cotton 331 and the second liquid-guiding cotton 332 are perpendicularly arranged and inserted into each other. The end of the second liquid-guiding cotton 332 away from the first liquid-guiding cotton 331 is located inside the mounting cylinder 35. The first liquid-guiding cotton 331 is installed on the mounting shell 32. The atomizing channel 31 passes through both ends of the middle part of the first liquid-guiding cotton 331. The second liquid-guiding cotton 332 is provided with a third ventilation groove 3321 arranged along the length direction. The third ventilation groove 3321 connects the atomizing channel 31 and the storage cavity 21.

[0039] In this embodiment, since the atomizing device 3 is connected to the outside and the third ventilation slot 3321 is connected to the atomizing device 3, the liquid supply device 2 and the atomizing device 3 form a communicating vessel with interconnected bottoms. When the user draws in through the air outlet 12, the external gas enters the atomizing channel 31 through the air inlet 11. At the same time, under the effect of the communicating vessel principle, there is a pressure balance between the liquid supply device 2 and the atomizing device 3, so that the atomizing medium in the liquid supply device 2 can continuously flow into the second liquid guide cotton 332 through the first liquid guide cotton 331. Then, the atomizing core 34 heats the atomizing medium to generate aerosol, and the aerosol is discharged outward through the air outlet 12.

[0040] In this embodiment, the synergistic effect of stable liquid guidance and smooth air exchange enables the aerosol generating device to continuously produce rich and uniform aerosols during use, resulting in a more delicate and mellow taste. It reduces the changes in suction resistance and aerosol volume fluctuations caused by liquid guidance and air exchange issues, providing users with a better smoking experience. This application cleverly integrates liquid guidance and air exchange functions without significantly increasing the volume of the liquid supply device 2 and the atomizing device 3, improving the utilization rate of the internal space of the oil cup, making the overall structure of the aerosol generating device more compact and simple, and facilitating production, manufacturing, and portability.

[0041] In this embodiment, the third ventilation groove 3321 increases the contact area between the aerosol generating medium and the second liquid guiding cotton 332, promoting the adsorption of the aerosol generating medium and thus improving the liquid guiding efficiency.

[0042] like Figure 6 As shown, the first ventilation groove 4 is further formed on the side wall of the first liquid-guiding cotton 331; the first ventilation groove 4 includes a straight groove 41 and a plurality of inclined grooves 42, the straight groove 41 penetrates the upper and lower ends of the first liquid-guiding cotton 331, the plurality of inclined grooves 42 are spaced apart on both sides of the straight groove 41, and the inclined grooves 42 communicate with the straight groove 41 and penetrate the side wall of the first liquid-guiding cotton 331.

[0043] In this embodiment, when the aerosol generating medium in the storage chamber 21 of the liquid supply device 2 decreases and forms a negative pressure, external air can be introduced through the straight groove 41, the inclined groove 42 and the second ventilation channel to balance the air pressure inside and outside the liquid supply device 2, thereby ensuring sufficient liquid supply to the atomizing device 3.

[0044] In this embodiment, the first ventilation groove 4 is composed of a tree-like structure formed by a straight groove 41 and an inclined groove 42, so that the first ventilation groove 4 extends from the air inlet 11 to various areas of the atomizing device 3, and increases the channel area and path diversity of gas exchange, which can more quickly discharge the gas in the atomizing device 3, so that the external gas can smoothly enter the atomizing device 3 along the first ventilation groove 4, and promote the gas in the atomizing device 3 to be introduced into the storage cavity 21 connected thereto.

[0045] Furthermore, the width of the straight groove 41 is 0.5 to 1.5 mm.

[0052] In this embodiment, the two inclined grooves 42 located on the same side of the straight groove 41 and adjacent to each other are arranged in parallel, so that the distribution of the inclined grooves 42 is uniform.

[0053] Furthermore, the distance between two adjacent inclined grooves 42 located on the same side of the straight groove 41 is 8.8 mm.

[0054] In this embodiment, the distance between two adjacent inclined grooves 42 located on the same side of the straight groove 41 is 8.8mm, so that multiple inclined grooves 42 are equidistantly arranged, and the first air exchange groove 4 extends from the air inlet 11 to various areas of the atomizing device 3.

[0055] like Figure 3 As shown, the second ventilation groove 5 is further formed on the inner wall of the mounting cylinder 35, and the opening of the third ventilation groove 3321 is oriented away from the second ventilation groove 5.

[0056] In this embodiment, the second ventilation groove 5 can effectively guide the aerosol generating medium from the storage cavity 21 to the atomizing core 34, and can also introduce external air when the aerosol generating medium in the storage cavity 21 reduces and forms a negative pressure.

[0057] like Figures 2-5 As shown, the liquid supply device 2 further includes a bottle body 23 mounted on the housing 1. The bottom of the bottle body 23 near the atomizing device 3 is provided with a docking cylinder 24.

A second sealing element 62 is provided between the docking cylinder 24 and the fixing cylinder 36.

[0062] In this embodiment, a fixed cylinder 36 and a second sealing element 62 are provided to further improve the sealing performance of the aerosol generating device.

[0063] like Figures 2-4 As shown, the housing 1 further includes an outer shell 13, an opening 14 on one side of the outer shell 13, a support plate 15 at the opening 14, a liquid supply device 2 placed on the support plate 15, and the liquid supply device 2 is engaged with the support plate 15 and the outer shell 13, the mounting shell 32 is located inside the outer shell 13, and the mounting cylinder 35 is located near the opening 14; the air inlet 11 and the air outlet 12 are respectively located at both ends of the outer shell 13, and the air inlet 11 is located at the end of the outer shell 13 where the support plate 15 is located.

[0065] Furthermore, the housing 1 also includes a base 16, on which an air passage 17 is provided. The air passage 17 is connected to the atomizing channel 31 and the air inlet 11 respectively. The base 16 is placed inside the outer shell 13 and abuts against the support plate 15. The mounting shell 32 is mounted on the base 16.

[0066] In this embodiment, when the user draws air through the air outlet 12, the external gas enters the air passage 17 through the air inlet 11 and then enters the atomization channel 31. There is a pressure balance between the liquid supply device 2 and the atomization device 3, so that the aerosol generating medium in the liquid supply device 2 flows to the atomization core 34 through the liquid guiding cotton component 33.
